Cell phone having an information-converting function

ABSTRACT

A voice discriminating tag for making a reception voice and a transmission voice distinguishable is added to the voice inputted into a cell phone. Further, a volume discriminating tag is added based on a detection result of a volume detector. A CPU converts the voice into character data and image data on the basis of the voice discriminating tag and the volume discriminating tag, referring to various files stored in file devices. The converted data is outputted to a display panel on which the character data corresponding to the transmission voice and the character data corresponding to the reception voice are shown in time series so as to have different colors. The character data is shown in a literal type corresponding to a volume level.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cell phone having a function forconverting voice information into character information.

2. Description of the Related Art

Some of cell phones comprise a function for converting inputted voiceinformation into character information. With respect to methods forconverting the voice information into the character information, variousmethods are conceived. For example, Japanese Patent Laid-OpenPublication No. 2002-116871 describes a system in that voice informationinputted into a portable device is sent to a server by means ofcommunication, and then, the voice information is converted intocharacter information by a voice-recognition device included in theserver. The converted character information is sent to the portabledevice and is shown on a display.

In the above-mentioned system, however, it is necessary to send thevoice information from the portable device to the server. Further, it isalso necessary to return the character information, which has beenconverted by the voice-recognition device, from the server to theportable device. Thus, there arises a problem in that it takes a time toobtain the character information. Moreover, there arises another problemin that quality of the voice information remarkably deteriorates and avoice-recognition rate of the voice-recognition device lowers becausethe voice information is transferred between the portable device and theserver through a public network.

A technology such as described in Japanese Patent Laid-Open PublicationNo. 2002-218092 is proposed for solving the above problems. In this kindof the technology, a portable device is provided with avoice-recognition device by which the voice information is convertedinto the character information. In virtue of this, the voice-recognitionrate may be prevented from lowering and the character information may bequickly confirmed.

However, in all of the above cell phones, either of reception voice andtransmission voice is merely converted into the character information.It is impossible to simultaneously convert the reception voice and thetransmission voice into the character information.

Further, it is impossible to express nuance of spoken language,emotional ups and downs thereof, etc. by the character information. Inother words, although a voice can freely express emotion and language tobe emphasized by changing voice volume of a talker, the above cellphones display the character information in a single font regardless ofstresses of the voice volume when the voice including the stresses isconverted into the character information. Thus, there arises a problemin that it is impossible to sufficiently express the emotion and thelanguage to be emphasized, because an expression mode of the characterinformation is poor in comparison with the voice. This kind of theproblem is similarly caused in a case the character information isinputted with keys or by hand.

SUMMARY OF THE INVENTION

In view of the foregoing, it is a primary object of the presentinvention to provide a cell phone in which character informationconverted by means of voice recognition has improved expressiveness.

In order to achieve the above and other objects, the cell phoneaccording to the present invention comprises a voice discriminator, avolume discriminator and a memory. The voice discriminator carries outvoice recognition relative to transmission voice information andreception voice information to convert it into character data forrepresenting character information. The transmission voice informationis inputted via a microphone, and the reception voice information isoutputted via a speaker. Also, the voice discriminator adds a voicediscriminating tag to the character data in order to distinguish eitherof the transmission voice information and the reception voiceinformation. The volume discriminator adds a volume discriminating tag,which represents a volume level of the voice information, to thecharacter data. The memory stores the character data, in time series, towhich the voice discriminating tag and the volume discriminating tag areadded.

In a preferred embodiment, a display type of the character informationis changed in accordance with the volume and voice discriminating tags.The character information is shown on a display in the different displaytype. In this case, at least one of a font, a character size and acharacter thickness of the character information is changed inaccordance with the volume discriminating tag. A display color of thecharacter information is changed in accordance with the voicediscriminating tag. Further, a specific word is converted into imagedata corresponding to the character data converted by the voicediscriminator. An image represented by the image data is shown on thedisplay.

The cell phone of the present invention may further comprise an emotiondeterminer, which determines an emotional state of a talker at the timeof phone call from the transmission voice information and the receptionvoice information. The emotion determiner adds emotion discriminatinginformation to the character data. The emotion determiner may alsodetermine an emotional state of a character-inputting person from aninputting manner of handwritten characters inputted via a touch panel.It is preferable to change at least one of a display font, a charactersize and a character thickness of the character information inaccordance with the emotion discriminating information. Further, aletter or an indicia defined every emotion discriminating informationmay be added to the character information.

Further, an e-mail producing unit may be included to produce e-mail byusing the character data, and an e-mail sending/receiving unit may beincluded to send and receive the produced e-mail.

According to the cell phone of the present invention, it is possible toproduce a record to which distinction of the voice is added. Thecharacter information is variedly expressed so that it is possible toproduce a record, which enhances the distinction of the voice and hasimproved expression. Since the display shows the image represented bythe image data, visual expression becomes affluent. Moreover, since thedisplay manner of the character is changed in accordance with theemotion of the talker, it is possible to improve the expression of thecharacter information obtained by the voice recognition. Furthermore, itis possible to produce the e-mail merely by the voice so that the e-mailmay be easily produced without a troublesome key operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

In FIG. 1, a cell phone 2 is constituted of an upper body 10 and a lowerbody 11, which are rotatably engaged with each other via a hinge 12. Arear side of the upper body 10 is provided with an antenna 13, and afront side thereof is provided with a speaker 14 and a display panel 15.As the display panel 15, a liquid-crystal panel (LCD) is used, forexample. The lower body 11 is provided with a microphone 16 and anoperating portion 19 including a selection key 17 (a portion surroundedby a chain line) and a dial key 18 (a portion surrounded by a two-dotchain line).

The hinge 12 is provided with a click mechanism (not shown) to retainthe upper body 10 and the lower body 11 at a predetermined angle such asshown in the drawing when the cell phone 2 is used. The cell phone 2 isfolded so as to confront the display panel 15 with the operating section19 when not used.

The speaker 14 outputs a voice of a calling party (a reception voice)and a ringing melody. The microphone 16 converts a voice of a talker (atransmission voice) into electric voice information. The selection key17 is operated when selecting and setting various menus for registeringa telephone number and a mail address, for instance, and when utilizingInternet-access service and e-mail service. Moreover, by operating theselection key 17, modes of a phone-call mode and a voice-recognitionmode are switched. In the phone-call mode, normal calling is performedthrough the voice. In the voice-recognition mode, the inputted voice isconverted into character data and image data. Meanwhile, when inputtinga telephone number and a sentence of e-mail, the dial key 18 isoperated.

The antenna 13 is drawn out of the upper body 10 at the time of making aphone call and utilizing the e-mail service and the Internet service.The antenna 13 receives radio-wave signals from the other cell phone, anInternet server and so forth, and sends radio-wave signals from the cellphone 2 to the outside. The antenna 13 converts the received radio-wavesignals into electric signals and transfers the signals to a CPU 20 viaa communication I/F 21, such as shown in FIG. 2. The CPU 20 controls anoperation of each section of the cell phone 2. For example, the CPU 20processes the signals transferred from the antenna 13 to output a voiceand an image to the speaker 14 and the display panel 15.

A data I/O 23 comprises a cable connection port 23 a and a loading gate23 b for various memory cards (see FIG. 1). The connection port 23 a isused for connecting with an external memory device and so forth. Thememory cards are an IC card, a smart medium, a memory stick and soforth. The data I/O 23 reads character data and image data from theabove-noted storage media. Meanwhile, the character data and the imagedata of the cell phone 2 are outputted to an external device via thedata I/O 23.

A menu picture including various setting menus is displayed on thedisplay panel 15 via a driver 22. Moreover, the display panel 15displays a telephone number of a calling party, a mail address, an imagedownloaded from the Internet server, and so forth via the driver 22.

A voice-recognition device 30 is constituted of a voice discriminator 30a and a volume detector 30 b. In the voice discriminator 30 a, voicerecognition is executed relative to transmission voice informationinputted from the microphone 16, and reception voice informationinputted via the antenna 13 to produce feature-quantity datarepresenting features of the voice information. Further, the voicediscriminator 30 a produces a voice discriminating tag in accordancewith the input of the voice information to distinguish either of thetransmission voice and the reception voice. In the volume detector 30 b,a volume level is detected from amplitude information of thetransmission voice information and the reception voice information toproduce a volume discriminating tag. The voice and volume discriminatingtags are added to the feature-quantity data.

A first file device 31 comprises a word-data file 31 a and an image-datafile 31 b. The word-data file 31 a includes the character datacorresponding to the feature-quantity data. The image-data file 31 bincludes the image data corresponding to the character data.Incidentally, the image data is properly used so as to correspond to aspecific word. For example, the image data is downloaded from theInternet server and is read out of the other storage medium via the dataI/O 23. Alternatively, a user may produce own image data by operatingthe keys of the operating portion 19.

A second file device 32 stores a setting-data file 32 a includingsetting data corresponding to the volume discriminating tag. The userselects in advance a type number of letters to be changed in accordancewith the volume level of the voice (hereinafter, called as “literal typenumber”). Further, the user also selects in advance a concrete style ofeach literal type (hereinafter, simply called as “literal type”). Thesetting data is stored in the second file device 32 as the setting-datafile 32 a.

The literal type is defined by combining designation informationconcerning a font, a literal size, boldface/lightface, an italic, anunder line, a frame line, hatching and so forth. For example, the volumelevel is classified into three steps, wherein the first step is thegreatest volume level, the second step is the secondary volume level tothe first step, and the third step is the smallest volume level. Whenthe literal type is changed in accordance with the respective steps, theliteral type number is three. For example, with respect to the literaltype corresponding to the first step, it is considered that thecombination is designated such that the font is Ming-cho type, theliteral size is 20 points, and the literal thickness is boldface. As tothe second step, the combination is designated such that the font isMing-cho type, the literal size is 12 points, and the literal thicknessis lightface. As to the third step, the combination is designated suchthat the font is Ming-cho type, the literal size is 9 points, and theliteral thickness is lightface. It is needless to say that the literaltype number is not exclusive to three in the present invention. Theliteral type number may be two and may be four or more. Further, theother font of Gothic, brush, round style and so forth may be used.

In accordance with the transmission and reception voices recognized bythe voice-recognition device 30, the CPU 20 executes proper processingalong a control program 33 a stored in a main memory 33. The CPU 20searches the word-data file 31 a of the first file device 31 on thebasis of the feature-quantity data transferred from thevoice-recognition device 30. Successively, the CPU 20 extracts thecorresponding character data. To the extracted character data, the voicediscriminating tag and the volume discriminating tag are added so as tocorrespond to the voice. Moreover, the CPU 20 searches the image-datafile 31 b of the first file device 31 on the basis of the extractedcharacter data. When there is the corresponding image data, the CPU 20reads this data.

Further, the CPU 20 searches the setting-data file 32 a of the secondfile device 32 on the basis of the volume discriminating tag added tothe extracted character data. Successively, the CPU 20 converts thecharacter data into predetermined literal-type data. Furthermore, theCPU 20 executes data processing on the basis of the voice discriminatingtag added to the extracted character data. When showing the letters onthe display panel 15, difference between the kinds of the voices(talkers) is adapted to be distinguishable. For instance, referring tothe voice discriminating tag, different color codes are added to thecharacter data of two sorts respectively corresponding to the receptionvoice and the transmission voice.

The character data for which data processing has been properly carriedout is transferred to a work memory 34 in time series. Meanwhile, whenthere is the image data converted from the specific word, the image datais also transferred to the work memory 34 together with the characterdata.

The CPU 20 reads the character data and the image data, which are storedin the work memory 34, in time series to produce a phone call file ofHTML format. The phone call file is sent to the driver 22 and is shownon the display panel 15.

The character data and the image data are sequentially shown as theletter and the image on the display panel 15 in time series. Inaccordance with the color code added to the character data, the letteris shown in a color corresponding to either of the transmission voiceand the reception voice. Further, the letter is expressed in the literaltype corresponding to the volume level.

Editing of the character data and the image data is done by operatingthe operating portion 19, viewing the letter and the image shown on thedisplay panel 15. A similar operation is carried out when the characterdata and the image data are produced and sent as e-mail. The e-mail iscreated by utilizing an e-mail producing unit 25. The produced e-mail issent by the CPU 20 to the public network (not shown) via thecommunication I/F 21 and the antenna 13. When sending and receiving thee-mail, the CPU 20 utilizes an e-mail sending/receiving unit 26. In themeantime, when the character data and the image data produced in HTMLformat have been received as e-mail, the received letter and image areviewed on the display panel 15 by handling the operating portion 19. Ina case that the received character data is produced in HTML format, itis possible to express the character data in the literal typecorresponding to the volume level, such as described in the above.Moreover, it is also possible to express the character data in adifferent color depending on the sort of the voice. When the characterdata and the image data obtained in this way are saved, the operatingportion 19 is handled to save them as permanent data in a memory device35 comprising an optical disk, a semiconductor memory and so forth.

Next, an operation of the above embodiment is described below, referringto a flowchart shown in FIG. 3. First of all, the cell phone 2 isconnected to the public network to start a phone call. When thereception and transmission voices are converted into the character dataand the image data, a voice conversion mode is set by handling theoperating portion 19. When the voice conversion mode is not selected, aphone-call mode is set to make a phone call without converting a callvoice into the character data and the image data.

Upon making the phone call under the voice conversion mode, thetransmission voice information and the reception voice information aresent to the voice-recognition device 30 in which the reception voice andthe transmission voice are separately recognized and thefeature-quantity data is produced. Moreover, the voice discriminatingtag is added to the feature-quantity data in order to make the receptionvoice and the transmission voice distinguishable. Further, the volumediscriminating tag is added on the basis of a search result obtained bythe volume detector 30 b.

The CPU 20 converts the voice into the prescribed character data and theprescribed image data, referring to the various files stored in thefirst and second file devices 31 and 32. Successively, the CPU 20converts the character data into the predetermined literal type, whichcorresponds to the volume level, on the basis of the voicediscriminating tag and the volume discriminating tag. At the same time,the CPU 20 adds the color code to the character data. In virtue of thecolor code, it is distinguishably shown on the display panel 15 that thecharacter data corresponds to which of the transmission voice and thereception voice. After executing the above processes, the convertedcharacter data and the converted image data are stored in the workmemory 34 in time series.

Then, the CPU 20 sequentially reads out the character data and the imagedata, which are stored in the work memory 34, in time series to show theletter and the image on the display panel 15 as the phone call file ofHTML format. The letter is shown on the display panel 15 in the literaltype corresponding to the volume level. The transmission voice and thereception voice are displayed in different colors.

Upon turning off the voice conversion mode by handling the operatingportion 19, the process for converting the call voice into the characterdata and the image data is over. When the converted character data andthe converted image data are not edited and are not saved, the processis returned. And then, if the voice conversion mode is selected again,the above-described process is executed. If this selection is not made,a normal phone call of the voice is carried out. When finishing thephone call, the operating portion 19 is handled to disconnect thenetwork.

When the character data and the image data are edited after turning offthe voice conversion mode, a predetermined operation is done with theoperating portion 19 to switch to an editing mode. Successively, theuser handles the selection key 17, the dial key 18 and so forth of theoperating portion 19 to edit the letter and the image, viewing themshown on the display panel 15. The CPU 20 executes an editing process ofthe letter and the image on the basis of a character-data editing signaland an image-data editing signal, which are sent from the operatingportion 19.

When the edited letter and the edited image are sent as e-mail, apredetermined operation is done with the operating portion 19 to switchto a mail-sending mode. After that, the character data and the imagedata are converted into a style of e-mail and are sent to the publicnetwork. Incidentally, the edited character data and the edited imagedata may be saved in the memory device 35 built in the cell phone 2.Alternatively, the edited data may be saved in an external memory devicevia the data I/O 23.

In this way, the reception voice and the transmission voice areseparately converted into the character data. Further, the differentcolor code is added to the converted character data. The character datato which the color code is added is displayed in time series.Consequently, letter strings respectively corresponding to thetransmission voice and the reception voice are displayed in differentcolors.

Since the display is performed in the literal type corresponding to thevolume level, the letter to be emphasized may be distinguished byviewing the literal form. Moreover, since the specific word included inthe voice is converted into the preset image data and is shown on thedisplay panel 15, it is possible to produce a memorandum having abundantpowers of expression.

In the above embodiment, the transmission voice and the reception voiceare displayed by the character data in the different colors, and theliteral type is changed to express the difference of the volume level.However, the sort of the inputted voice may be distinguished by changingthe literal type, and the volume level may be expressed in the differentcolor. To conclude, any expressing manners may be adopted on conditionthat the volume-level expressing manner is different from the voice-sortexpressing manner.

In the above embodiment, the phone call file is produced in the HTMLformat. However, XML format may be adopted. Moreover, a switch forchanging the HTML format to a text format may be provided, and the phonecall file may be produced in the text format.

In the above embodiment, the image corresponding to the specific word isdisplayed. However, the specific word may be converted into a specificletter string.

A second embodiment is described below. FIG. 4 shows an electric blockdiagram of a cell phone 40 in which a display form of letters is changedin accordance with emotion of a talker. The cell phone 40 comprises avoice-recognition device 41 including a voice discriminator 41 a, avolume detector 41 b and an emotion determiner 41 c. The voicediscriminator 41 a and the volume detector 41 b are respectivelyidentical with that of the first embodiment (see FIG. 2) so thatdetailed description thereof is abbreviated. Further, the othercomponents except the voice-recognition device 41 are identical with thefirst embodiment so that the respective components are denoted by thesame reference numeral and detailed description thereof is abbreviated.

On the basis of voice data inputted by a transmitter and a receiver, theemotion determiner 41 c records a volume, a phone-call speed and anintonation in real time. When the phone call has been over, mean valuesof the volume and the phone-call speed are calculated. Alternatively,the mean values may be calculated at regular intervals. Successively, afluctuation amount from the mean value is calculated regarding therecorded voice data to discriminate the emotion of the talker on thebasis of the calculated fluctuation amount. For example, when thephone-call volume is extremely higher than the mean value, it isdetermined that the talker is angry. Incidentally, the mean values ofthe volume and the phone-call speed may be calculated from voice samplesinputted by the transmitter and the receiver prior to the phone call.

In the emotion determiner 41 c, the estimated emotion of the talker isrecorded as an emotion discriminating tag so as to correspond to thecharacter data. The emotion discriminating tag is classified intocategories of laugh, sorrow, anger and surprise, for instance. By theway, the emotion of the talker may be estimated from a laughing voice, avoice of crying and a voice of surprise besides the phone-call speed,the volume and the intonation. Further, the emotion of the talker may berecorded as the emotion discriminating tag by estimating the emotion ofthe talker from contents of the phone call after conversion to thecharacter data.

In the second file device 32, display-type data concerning the font, thethickness and the color of the letter is recorded for each emotiondiscriminating tag. The CPU 20 changes the display type of the characterdata in accordance with the obtained emotion discriminating tag andsends it to the work memory 34.

Besides changing the display type of the letter, a character and anindicia may be added. For instance, the character and the indicia ofso-called emoticon or the like may be added to the end of a sentence.When a certain sentence includes the emotion discriminating tagcorresponding to “laugh”, the character data of “(laugh)” or“({circumflex over ( )}o{circumflex over ( )})” is added to the end ofthe sentence. When a certain sentence includes the emotiondiscriminating tag corresponding to “sorrow”, the character data of“(sorrow)” or “(T₁₃ T)” is added to the end of the sentence. Further,when the contents of the phone call are sent by e-mail, the indicia maybe automatically added to a title of e-mail in accordance with theemotion discriminating tag included in the transmission character data.Furthermore, when incoming mails are listed, it is possible toautomatically show the indicia predetermined in accordance with theemotion discriminating tag.

In the second embodiment, the emotion of the talker is estimated fromthe phone-call voice. However, the emotion of the user of the cell phonemay be estimated from an input manner of a letter inputting device, andthe display form of the letter may be changed in accordance therewith.FIG. 5 shows a block diagram of a cell phone 50 according to a thirdembodiment. The cell phone 50 is identical with that of the firstembodiment (see FIG. 2) except for a touch panel 51 for inputtingcharacters, an input-data analyzer 52, a character-recognition device53, and a dictionary 54 for recognizing the character.

The input-data analyzer 52 detects analog data inputted into the touchpanel 51 via a dedicated pen. The detected analog data is transferred tothe character-recognition device 53 wherein the inputted analog data iscollated with the dictionary 54. And then, the display panel 15 showsnominated letters, which have been judged as being close to the inputteddata, to notify the user that which one should be selected.

In the input-data analyzer 52, data concerning an input speed, a penpressure and a size is recorded whenever the character is inputted viathe touch panel 51. When the character has been inputted, mean values ofthe input speed, the pen pressure and the size are calculated.Alternatively, the mean values may be calculated at regular intervals.The input-data analyzer 52 estimates the emotion of the user at the timeof inputting, from a fluctuation amount relative to the mean values ofthe input speed, the pen pressure and the size. For example, when theinput speed is larger than the mean value, it is judged that the user isin a hurry. In contrast, when the input speed is smaller than the meanvalue, it is judged that the user is calm. Further, when the inputtedletter is judged as being neat (namely, a matching rate of the nominatedletter is high), it is judged from careful input that an importantmatter is inputted. In contrast, when the inputted letter is sloppy(namely, the matching rate of the nominated letter is low) and when thepen pressure is extremely high, it is judged that the emotion is high.

Emotional information of the user judged in this way is related to thecharacter data as the emotion discriminating data, on the basis of whichthe display form of the letter including the font, the thickness and thecolor is changed. In virtue of this, the inputted letter may beabundantly expressed.

When it is necessary to concurrently carry out the other processes of avoice-recognition process, a phone-call process and so forth in additionto the character input/recognition processes, priority of the characterrecognition process may be changed in accordance with the emotiondiscriminating data. In other words, when the input speed is fast, it isjudged that the inputted document is important, and the characterrecognition process is preferentially carried out. When the pen pressureis high, it is judged that the emotion is high. In this case, a stressof the user to be caused due to wait may be relieved by preferentiallycarrying out the character recognition process. Meanwhile, when theinput speed is slow, it is judged that the user inputs with thinking. Insuch a case, since input of a sentence might be redone, the priority ofthe character recognition process may be lowered. Further, a message forconfirming a procedure of the character recognition process may bedisplayed for the user. By doing so, the other processes are efficientlycarried out.

The above embodiment relates to the cell phone of the handwriting-inputtype. This embodiment, however, is similarly adopted to another type inthat the character is key-inputted via the operating portion 19. It ispossible to effectively carry out a plurality of processes by changingpriority of conversion processes in accordance with an input speed ofkeys and a pressure for pressing the key.

The above embodiments relate to the cell phone. The present invention,however, is similarly adopted to portable electronics devices of a PDA(Personal Digital Assistant), a digital camera and so forth.
